No. Though economic precariousness is the dominant reason, yet there are other reasons such cultural, psychological, geopolitical, etc. for social exclusion.

The correct answer is no. Social exclusion is primarily a survival mechanisms derived from the times when group cohesion was important for food gathering and survival. As a result we have in group and out group attitudes common to all social groups. Our genes have not kept pace with our socioeconomic environment. However, lower socioeconomic groups fare worst as a result of group identity and cohesion, and it may appear that money is responsible, but other factors are of greater importance.

No, social exclusion could be related to multiple reasons including local government policies, and social structures and stratification

La exclusión social va más allá de la cuestión económica, lógicamente la pobreza genera per se exclusión social pero existen desigualdades que también generan exclusión social como el género, la etnia, la religión, la región geográfica en fin, son muchas y que cuando se unen se potencian.

They are different economic and social processes. Perhaps you may apply Castel’s distinction between three ‘zones’ of contemporary societies (2003, pp. xv-xvi): the ‘zone of integration’ (people with stable work and long-lasting social relationships); the ‘zone of social exclusion’ (absence of any participation in productive activities and relative social isolation); and the ‘zone of vulnerability’ (non-standard employment contracts, economic insecurity, and fragile social relationships). The recurrent economic crisis has weakened the ‘zone of integration’, reducing social groups' relevance with highly-protected jobs and high welfare protection levels. Concurrently, the recurrent crisis has expanded the ‘zone of vulnerability’, produce more precarity than exclusion.

No, economic precariousness is not the only reason for social exclusion. Racial, ethnic, linguistic, gender, religious, sexual identity, and many other individual and structural factors can be reasons for social exclusion.

No, as a member of Rosenet COST project I can suggest to read reseach papers of influing 5 factors to social exclusion of elderly http://rosenetcost.com/knowledge-synthesis-papers/

I dont think so, there could be other reasons for social exclusion where mobility, identity, one's social background, education, use of any language, representation, and consumer habits could be other reasons for social exclusion. Exclusion is something that is relative in nature and contextual too. Social Inclusion on the other hand also develops the other kind of exclusion.

The question is imprecise. What is social exclusion? You use the term as if it were self-explanatory. Unfortunately, this is widespread, as can also be seen from the previous answers. What context is meant when we speak of 'social'? What does 'excluded' mean and what does 'included' mean? These are not permanent, aggregate-like states. No one is permanently excluded or included in an overall social context, only in different sub-contexts of society. If participation in social life is not successful in different contexts, this can be due to various factors, not only economic ones. For example, it can also be cultural, religious, educational, physical, psychological, legal or political factors.

There are social groups that are involved in processes of exclusion and groups with an integration that presents high instability in many spheres of their life. Many social groups are not excluded; they do not live at the margins of society, in separate spheres, and are not socially isolated as the poor of the ghetto described by Wilson. They take part in social life though in constant insecurity: the working conditions expose them inevitably to sudden fluctuations of income and in other spheres of life they experience similar precariousness. Rather than a rupture of social ties produced by processes of exclusion, the most critical dynamics of their living conditions is precarity and the accumulation of many insecurities in many spheres of life. Though weak, their ties are nevertheless resources for a way out.

Si dans les industrialisés capitalistes le facteur économique est déterminant dans beaucoup de sociétés des pays du Sud la dimension socioculturelle est encore très prégnante dans l'exclusion de certains groupes sociaux au delà de leur réussite économique
